JAMES ANDREW GRACE, OF DE KALB, MISSISSIPPI.

COTTON-CHOPPER.

To all whom it may concern:

Be it known that I, JAMES ANDREW GRACE, a citizen of the United States,residing at De Kalb, in the county of Kemper and State of Mississippi,have invented certain new and useful Improvements in Cotton-Choppers;.and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in cotton scrapersand comprises various details of construction and combinations andarrangements of parts which will be hereinafter fully described and thenspecifically defined in the ap pended claim. I

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view of the ap paratus. Fig. 2 is a sectional view, andFig. 3 is a detail view.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the apparatus having standards B and G to whichthe handles D are fastened. A shaft F is journaled in, suitable bearingsupon said frame and has wheels F fixed thereto.

Mounted in suitable bearings in the crosspieces K of the frame is alongitudinally disposed rotatable shaft K having the chopper blades Nfastened thereto in any suitable manner. The opposite ends of thecrosspieces K are recessed away as at K for the reception of the sideportions of the frame to which they are fastened. A pinion wheel 0 isfixed to the end of the shaft K and meshes with a pinion wheel F uponthe shaft F and afi ords means whereby motion may be transmitted fromthe shaft F to the shaft carrying the chopper blades.

The forward portion of the frame of the apparatus is tapering and stripsQ, are held parallel to and spaced apart from each tapering portion ofthe frame, as shown clearly in the drawings, and between whichSpecification of Letters Patent.

strip and tapering portion of the frame are adjustably held theapertured plates S in which the knees T carrying the scrapers T areadjustably held. Said plates S are of such a thickness as to fit snuglythe space intermediate the strips Q and the upper face of the frame andupon the contracted threaded projections of each plate S a tighteningnut S is mounted and adapted, as they are turned against the inner edgesof the strips Q, and the inner marginal edges of the tapering portionsat the forward end of the frame to clamp the inner edges of the kneesagainst said strips and the outer inclined edges of the taperingportions of the frame, thereby securely holding the knees in adjustedpositions.

By the provision of an apparatus as shown and described, it will benoted that the scrapers, each having a plurality of knees fastenedthereto, may be rigidly held in various adjusted positions as may bedesired to operate upon rows different distances apart and may be raisedand lowered to hold the scraper in different positions, while the rotarychopper is adapted to out the soil in the usual manner.

What I claim to be new is In combination with the frame of a cottonscraper, the forward portion of which has inclined portions which aresubstantially at right angles to each other, strips fastened upon theupper faces of said inclined portions of the frame and spaced aparttherefrom, scrapers, a plurality of knees fastened to each scraper,plates having apertures for the reception of said knees and adjustablymounted between said strips and the portions of the frame underneath thesame, the shank portions of said plates being contracted and threaded,and nuts mounted upon the threaded portions and bearing against theinner marginal edges of the strips and the inner faces of the in clinedportions of said frame.

In testimony whereof I hereunto affix my signature in the presence oftwo wltnesses.

JAMES ANDREW GRACE.
